Use with the SDK

Install @pipeworx/sdk to call tools from any TypeScript/Node project.

TypeScript 
import { Pipeworx } from '@pipeworx/sdk';
const px = new Pipeworx();
const result = await px.call("estimate_electricity", {});
ask_pipeworx 
// Or ask in plain English:
const answer = await px.ask("carbon interface mcp — carbon interface api (v1)");
